BOTTLE-RINSING MACHINE.

Application filed October 18, 1927, Serial No. 227,017, and in Sweden October 19, 1926.

Bottle-rinsing machines are known, in which the bottles are being immersed in a bath of lye or another suitable rinsing fluid, the bottles being carried in holders titted to a pitchchain running over wheels in and above the bath. The holders are so fastened to the chain that the bottles, when entering the bath, will be filled with lye, whereas they are emptied, when the chain mounts. It has been found the bottles will not be effectively rinsed in such machines, owing to the rinsing fluid not being injected with sufficient force.

The present invention has for its object in this respect to improve the said machines by applying to the nave of one or more of the chain-wheels a number of tubes, into which rinsing fluid is forced by pressure in order that it may be thrown into the bottles through suitably arranged holes or orifices in the tubes. These tubes are, of course, so

arranged as to number and location in relation to the teeth of the wheel, that the mouth of a bottle comes ri ht before the orifice of that tube which at the moment communicates with the pressure-tube for the rinsing fluid.

The accompanying drawing illustrates the invention in Figs'l and 2 showing two sections of the machine at right angles to each other, the line yy representing the level of the bath. 1 denotes the chain, 2 the holders,

3 the bottles, and 4 one of the cl'iain-wheels above the bath. The nave 5 is by means of gudgeons (5, 7 carried by pillow-blocks 8, 9.

The gudgeon 6 is hollow and receives the outer end 10 of the pressure-pipe 11, this end 10 being shaped like the plug of a cock.

Both the pipe 11 and the plug 10 are stationary, the latter being provided with an opening 12 communicating with channels 13 in the nave 5 and opening into tubes 14 round the nave parallel to the centre-line and rigidly connected with the nave and arranged with respect to their number and positionsin the manner stated above. The tubes are provided with holes or orifices, through which rinsing fluid is forcibly thrown into the bottles Guides or positioning devices or the like 15 are provided for uidin the bottles in ri 'ht )ositions. O D O The working of the machine will be seen from its construction.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. Bottle washing apparatus, including a conveyor chain having uniformly spaced bottle receiving pockets, said conveyor including a rinsing sprocket wheel comprising a rotatably mounted nave, spaced tubes arranged about said nave parallel to the axis thereof and being provided with parts adapted to register with and discharge into the months of the bottles entrained about said sprocket, and means for supplying fluid under pressure to said tubes, substantially as set forth and shown.

2. Bottle washing apparatus, including a conveyor chain having uniformly spaced bottle receiving pockets, said conveyor including a rinsing sprocket wheel comprising a. rotatably mounted nave, spaced tubes arranged about said nave parallel to the axis thereof and being provided with parts adapted to register with and discharge into the mouths of the bottles entrained about said sprocket, the said sprocket wheel having one of its gudgeons hollow and receiving a plug constituting the end of a pressure-conduit for the rinsing fluid and having an opening which by channels through the said naive communicates with the discharging tubes.

In testimony whereof I have signed my name to this specification.
